[issue11466] getpass.getpass doesn't close tty file

I think I've found the root cause.

On my system (also tested in 3.2) /dev/tty is opened successfully, but wrapping it in io.BufferedRandom fails. By the time the exception is raised, FileIO object is already created, and then it immediately gets deleted.

I'm attaching a patch that closes the file explicitly in this case.
Be extra careful when reviewing though - this is the first time I'm touching Python's C code.
